Personal Care Raw materila Polyvinylpyrrolidone K90

Details:

Polyvinylpyrrolidone(PVP)  are existing as powder and water solution form,and being supplied in a wide molecular weight range,easily dissolve in water,alcohol and other organic solvents,highly hygroscopicity,excellent film-forming capacity,adhesiveness and chemical stability,none toxicity.Cosmetic Grade PVP are widely used in hair care,skin care and oral care products,especially for hair styling products.In view of it’s wide molecular weight range,from the low molecular weight to high molecular weight PVP applicable for soft to hard hair care products’ formulations.

PVP Polymer is a hygroscopic polymer ,supplied in white or creamy white powder,raning from low to high viscosity & low to high molecular weight with solubility in aqueous and organic solvents,each characterized by K Value.

Properties:
*Solubility in water and many oter organic solvents.
*Hygroscopicity
*Film former

Applications:
1) In Pharmaceutical Field:
*Binder for tablets,the premier high performance binders for wet granulation.
 
*Films/Sugar coatings,act as film-forming agents,adhesion promoters and pigment dispersers.
 
*Viscosity modification,crystal inhibitors and drug solubilization in liquid formulations,such as injection and ophthalmic products.
 
*Thickening agents for aqueous-alcoholic solutions for oral and topical preparations.
 
*Improve solubility and enhances bioavailability of drug actives,used to adjust the solubility speed of some hardly soluble actives to enhance bioavailability.
 
*Pore formation in taste-masking formations,medical plastics and in other membrane production.
 
*Others,capsule flow aid,cleaning fluids for contact lenses,enzyme and sensitive medicines stabilization,cryoprotector.

2)In Cosmetic Filed:
Cosmetic Grade PVP products are suitable for fourmulations which used as film forming and viscosity modification,especially in hair styling products,mousse gels and lotions & solution,PVPs also used as dispersion agent in Hair-dying,pigment products' formulations.Thickening agent for oral and optical preparations.

3)In Hi-Tech Industries:

Technical grade PVP are being used Textiles/Fibers,Adhesives,Coatings/paintings,Laundry/Household detergent,Inks,Ceramics and other hi-tech industries.

*Dye transfer inhibition in detergents using PVP K15,K17 & K30 and/or its liquid product to complex fugitive.

*Textile dye stripping and strike rate control through compexation and dispersion with PVP K30 and/or its liquid product.

*Laundry detergents where PVP K30 inhibits soil redeposition.

*Emulsion polymerization where PVP K30 and or its liquid product latex stabilizer,functioning as a protective colloid,facilitates redispersion of a 'broken'latex end-use application.

*Dispersions using PVPK30 & K90 and/or its liquid product for nonaqueous dye and pigment-based writing ink delivery systems.

*Hollow fiber membrane manufacture in which PVP K90 & K30 and/or its liquid product create voids any hydrophilic domains in polysulfone membranes.

*In oil filed cementing,where PVP K30& K90 and or its liquid productserve as fluid loss control agents.

*On lithographic plates using hydrophobic inks,where PVPK15 provides enhancement of the nonimage area.

*PVP K80,K85 & K90 and/or its liquid products in stearate-based adhesive sticks for arts and crafts applications.

*In fiber glass sizing,using PVP K30 & K90 and/or its liquid products film forming action to promote polyivnylacetate adhesion.

*As combustible ceramic binders,using PVP K30 & K90 and/or its liquid product to enhance green strength.

*PVP K15,K17,K30,K60 & K90 and/or its liquid products used in agriculture as binder and complexation agent for crop protection,Primary film former in seed treatment and coatings.
